Wingers Adam Ashley-Cooper and Nick Cummins, front-rowers Tatafu Polota-Nau, Benn Robinson and Paddy Ryan and flanker Liam Gill have all been suspended for one match.

Of the six, only Ryan will be available for the match against the Scots at Murrayfield this weekend, instead missing the final match of their tour against Wales.

The Wallabies were forced to delay his suspension for an extra week because otherwise they wouldn't have enough props available.

Other players were warned about their conduct. Dave Dennis, Kane Douglas, Saia Fainga'a, Bernard Foley and Nick Phipps were given written warnings, and Scott Fardy, Mike Harris, Ben McCalman and Nic White were spoken to.

Coach Ewen McKenzie said: "Everyone in our squad is required to comply with and adhere to high standards of ethical conduct both on and off the field.

"Those standards were compromised in the lead-up to Saturday's victory over Ireland with a group of players making the decision to stay out late and consume inappropriate levels of alcohol during the early hours of Wednesday morning.

"The Qantas Wallabies, in conjunction with the ARU, have decided to take significant action in a quest to drive the highest standards off the field.

"Let's be clear - these are internal sanctions and aren't a result of any complaints or reports of inappropriate or sinister behaviour while our players were out.

"Instead, we have chosen to address an issue that has come up internally and we are now being up-front about it.

"We've done this because we need to continually reinforce the need for our players to make smart decisions to benefit the team.

"The worst thing you could do for the Qantas Wallabies in the long-term is do nothing because that would mean we would be ignoring poor culture and a significant performance issue.

"We will always take action in relation to examples of poor culture when it's warranted - doing nothing to address poor behaviour will never be an option. We've taken on the challenge of re-defining our team culture.

"This is not a simple process but it needs to happen so we can have a chance to be the best team we can be.

"Already this year we've spent a lot of time being crystal clear around behaviours to ensure we are in a position to take the step-up to the next level.

"The reality is that if we are going to reach these levels, the players need to be making the right decisions as professional athletes and need to do everything possible to perform at their best for each Test."
